Effect of a multifaceted stewardship intervention on antibiotic prescribing and outcomes for acute bacterial skin and skin structure infections

Background: Acute bacterial skin and skin structure infections (ABSSSI) are a leading cause of hospitalization, but are often treated inappropriately in the inpatient setting. A multifaceted stewardship intervention was implemented to encourage prescribing of guideline-concordant therapy (GCT). Objective: To examine the impact of this initiative on antimicrobial prescribing practices and patient outcomes. Methods: This was a single-center, retrospective study of adult inpatients admitted with a primary or secondary diagnosis of ABSSSI, classified by type and severity based on signs of systemic infection. Patients treated during the pre-intervention period (pre-IP) were compared with patients treated during the post-intervention period (post-IP). The primary endpoint was receipt of GCT. Secondary endpoints included receipt of anti-anaerobic antibiotic (AAA) or broad-spectrum antibiotics (BSA). Results: A total of 125 patients were included, 64 in the pre-IP and 61 in the post-IP. There was a statistically significant increase in prescribing of GCT during the post-IP compared with the pre-IP (14% versus 56%, p < 0.0001) and a decrease in use of AAA (56% versus 34%, p = 0.01). No difference was observed with use of BSA (16% versus 15%, p = 0.89). Use of the computerized order set during the post-IP was low (18%). There was a numerical, but non-significant reduction in 30-day readmission (14.1% versus 6.6%, p = 0.17). Conclusion: The multifaceted intervention was effective for improving prescribing of GCT for ABSSSI. Given low use of the computerized order set, improved prescribing seemed to be driven by provider education. Strategies around ongoing education may be key to sustain positive results of stewardship interventions.

Purpose: Following updates to the Infectious Diseases Society of America (IDSA) practice guidelines for the Diagnosis and Treatment of Adults with Community-acquired Pneumonia in 2019, Hartford HealthCare implemented changes to the community acquired pneumonia (CAP) order-set in August 2020 to reflect criteria for the prescribing of broad-spectrum antimicrobial therapy. The objective of the study was to evaluate changes in broad-spectrum antibiotic days of therapy (DOT) following these order-set updates with accompanying provider education. Methods: This was a multi-center, quasi-experimental, retrospective study of patients with a diagnosis of CAP from September 1, 2019 to October 31, 2019 (pre-intervention) and September 1, 2020 to October 31, 2020 (post-intervention). Patients were identified using ICD-10 codes (A48.1, J10.00-J18.9) indicating lower respiratory tract infection. Data collected included demographics, labs and vitals, radiographic, microbiological, and antibiotic data. The primary outcome was change in broad-spectrum antibiotic DOT, specifically anti-pseudomonal β-lactams and anti-MRSA antibiotics. Secondary outcomes included guideline-concordance of initial antibiotics, utilization of an order-set to prescribe antibiotics, and length of stay (LOS). Results: A total of 331 and 352 patients were included in the pre- and post-intervention cohorts, respectively. There were no differences in order-set usage (10% vs 11.3%, P = .642) between the pre- and post-intervention cohort, respectively. The overall duration of broad-spectrum therapy was a median of 2 days (IQR 0-8 days) in the pre-intervention period and 0 days (IQR 0-4 days) in the post-intervention period ( P < .001). Patients in whom the order-set was used in the post-intervention period were more likely to have guideline-concordant regimens ([36/40] 90% vs [190/312] 60.9%; P = .003). Hospital LOS was shorter in the post-intervention cohort (4.8 days [2.9-7.2 days] vs 5.3 days [IQR 3.5-8.5 days], P = .002). Conclusion: Implementation of an updated CAP order-set with accompanying provider education was associated with reduced use of broad-spectrum antibiotics. Opportunities to improve compliance and thus further increase guideline-concordant therapy require investigation.

Conclusion Despite low utilization of the order-set, education surrounding order-set changes appeared to improve antibiotic prescribing and hospital LOS in our population. Further opportunities to improve order-set use and thus further increase guideline-concordant therapy are still available. Disclosures Joseph L.

The Impact

Abstract Background Treatment of asymptomatic bacteriuria (ASB) outside of pregnancy and urological procedures increases the risk of antibiotic resistance without improving outcomes. At Olive View-UCLA Medical Center (Sylmar, CA), the CDC U.S. Antibiotic Awareness Week (AAW) was utilized as a platform to promote antimicrobial stewardship (AS) for ASB. We evaluated the incidence of antibiotic treatment of ASB pre-AAW vs post-AAW, and the impact of AS education on future prescribing practices for ASB. Methods In this single-center retrospective observational study, AS education defining ASB vs urinary tract infection (UTI) was provided via visual aids distributed throughout the hospital during AAW from 11/18/2020 to 11/24/2020 (Figure 1). All positive urine cultures (Ucx) for adult inpatients were reviewed prior to AAW from 9/2020 to 11/2020 and after AAW from 12/2020 to 1/2021. Patients were excluded if they were unable to report UTI symptoms, pregnant, or undergoing urological procedure. The incidence of ASB treatment pre- and post-AAW was compared. A survey was sent to providers to compare the impact on antibiotic prescribing behavior for ASB pre- and post-AAW. Fisher’s exact and Chi-squared tests were used for statistical analysis. Figure 1. Antimicrobial Stewardship Education and Poster Distribution Results A total of 260 cases met study eligibility. In the pre-AAW group, 56 of 131 cases presented with ASB, of which 16 were treated with antibiotics (28.6%). In the post-AAW group, 55 of 129 cases presented with ASB, and 5 were treated with antibiotics (9.1%). Antibiotics were prescribed more often for patients with ASB in the pre-AAW group compared to those in the post-AAW group (p=0.014). Forty providers completed the survey, of which 97.5% had seen the visual aids, 70% had found the education "very” or “extremely" useful, and 43.6% reported they “always or sometimes” treated ASB pre-AAW vs 15% post-AAW (p< 0.01). Conclusion AS posters and education defining ASB significantly decreased the treatment of ASB. AAW education on ASB antimicrobial stewardship demonstrated a high value and shifted prescribing behavior to avoid antibiotic treatment of ASB. A similar approach to deliver provider education could serve as a valuable model to change provider AS practices for ASB. Disclosures All Authors: No reported disclosures

Abstract Background Almost half of urine cultures (UCs) obtained are in asymptomatic patients, which may lead to misdiagnosis of urinary tract infection (UTI) and unnecessary treatment. To decrease misdiagnosis of UTI, changes were made to the order entry and urine culture process at our institution in April 2018. This included removal of a standalone UC from the electronic order entry system and development of a more stringent criterian for urinalysis with reflex culture (UAC). We evaluated the impact of these ordering changes on the total number of UCs performed. Methods This was a pre-post retrospective study comparing the hospital UAC rate per 1,000 patient-days and ED UAC rate per 1,000 visits in the pre-intervention period from April 2017 to March 2018 to the intervention period from May 2018 to March 2019 in a 319-bed teaching hospital in northwest Ohio. In April 2018, urine microscopy and UAC were the only available options. Furthermore, UC would only be performed if the following criteria were met: 10 white blood cells (WBC)/HFP. Standalone UC was available for the following patients who were excluded: immunosuppressed patients, pregnant women and patients undergoing invasive urologic procedures. These changes were accompanied by provider education, and providers were given the option to override UAC rules by calling the microbiology lab within 24 hours to request UC. Results After incorporating these changes, we observed an increase in the use of UAC compared with UC-only in both the ED (80% pre-vs. 94% post-implementation) and inpatient setting (59% pre-vs. 92% post-implementation). This was accompanied by a reduction in the overall UCs performed in both the ED (49.17 per 1,000 visits to 23.53 per 1,000 visits [P < 0.001]) and inpatient units (23.31 per 1,000 patient-days to 9.31 per 1,000 patient-days [P < 0.001]). Chart review of cases where providers overrode UAC criteria and requested UC have demonstrated no false negatives to date; cultures either had no growth or were consistent with contamination by polymicrobial urogenital flora. Conclusion Restricted access to standalone UC, implementation of UAC with more stringent criteria and provider education reduced the number of urine cultures performed without sacrificing sensitivity for detecting UTI and potential antimicrobial use.

Abstract Background C. difficile infection (CDI) is a common healthcare-associated infection and quality measure for hospitals. Diagnosis of CDI is challenging as testing modalities, i.e., nucleic acid amplification test (NAAT), are highly sensitive but cannot differentiate between colonization and infection. Therefore, judicious use of testing is critical to avoid unnecessary diagnosis and treatments. Methods This single-center, retrospective chart review evaluated the impact of a two-step diagnostic stewardship intervention on C. difficile diagnosis and use of oral vancomycin in the inpatient setting. For the first step of the intervention, providers were educated on appropriate diagnosis and treatment, and given access to an optional electronic CDI clinical decision support system (CDSS). For the second step of the intervention, the CDI NAAT stand-alone testing option was removed from the lab ordering menu and providers were required to use the CDSS to order testing. Clinical data including bed-days of care (BDOC), total number tests ordered, number of positive tests and use of oral vancomycin was collected for the pre-intervention period (1/1/16 – 3/31/17), post intervention period 1 (April 1, 2017–October 31/18) and post-intervention period 2 (November 1, 2018–March 31, 2019). Results Compared with the pre-intervention group, there were no significant differences in the number of total CDI NAATs ordered, positive CDI NAATs or vancomycin DOT/10,000 BDOC in post-intervention group 1. There was a reduction in the number of total CDI NAATs ordered (341 vs. 42 [87.7%]) and the number of positive CDI NAATs (56 vs. 7 [87.5%]) in post-intervention group 2, respectively. When this data were normalized based on bed days of care (BDOC), there were still significant reductions in NAATs ordered and number of positive CDI NAATs (64 vs. 27 [57.8%]; 11 vs. 5, respectively, [54.5%]) and with vancomycin oral DOT/10,000 BDOC (72 vs. 7 [90.3%]) (Table 1). Conclusion Provider education and an optional CDSS did not significantly impact CDI NAAT ordering or use of oral vancomycin for CDI. However, implementation of a mandatory CDSS for CDI testing was shown to significantly decrease the number of tests ordered, the number of positive tests, and the use of oral vancomycin.

Order Set

Abstract Background The Surviving Sepsis Campaign Guidelines recommends administration of broad-spectrum antibiotics within 1 hour of sepsis diagnosis; electronic order sets drive antibiotic selection with pre-populated regimens based on the suspected infectious indication. Given the low rate of cephalosporin cross-reactivity in patients with a PCN allergy, we modified our ED sepsis order set (Images 1 and 2) to include cephalosporin options in patients with reported mild-to-moderate PCN reaction histories. This was a single-center, retrospective analysis evaluating the impact of this change on antibiotic prescribing and associated outcomes. Methods An electronic medical record (EMR) report identified patients ≥18 years of age with a documented PCN allergy that received antibiotics via the ED sepsis order set from December 30, 2012 to September 28, 2013 (pre-intervention) and January 3, 2014 to July 18, 2015 (post-intervention). The primary objective was to compare antibiotic days of therapy (DOT) and length of therapy (LOT) between the pre- and post-groups. The secondary objectives included 30-day readmission and mortality, hospital length of stay (LOS), incidence of C. difficile within 6 months and documented hypersensitivity reactions. Bivariate analyses, with chi-square, Mann–Whitney U, and Poisson means test, were used. Results A total of 180 patients (90 pre- and 90 post-intervention) were included. Demographics were similar between groups, with the exception of congestive heart failure (CHF) which was more prevalent in the post-intervention group (P = 0.039). Aztreonam, vancomycin, aminoglycoside, and fluoroquinolone DOTs were significantly reduced (P < 0.001) while cephalosporin DOTs significantly increased (P < 0.001) in the post-intervention group. There were no statistical differences in antibiotic LOT, 30-day readmission and mortality, hospital LOS, or incidence of C. difficile infection. For those patients that received cephalosporin antibiotics, there were no hypersensitivity reactions documented in the EMR. Conclusion Stratifying ED sepsis order sets by PCN allergy history severity is a safe and effective intervention that reduces second-line antibiotics in PCN allergic patients presenting to the ED with suspected sepsis.

Abstract Background Inappropriate antibiotic prescribing is an important modifiable risk factor for antibiotic resistance. Approximately half of all antibiotics prescribed for acute respiratory infections (ARIs) in the United States may be inappropriate or unnecessary. The purpose of this quality improvement (QI) project was to evaluate the effect of three consecutive interventions on improving antibiotic prescribing for ARIs (i.e., pharyngitis, rhinosinusitis, bronchitis, common cold). Methods This was a pre-post analysis of an antimicrobial stewardship QI initiative to improve antibiotic prescribing for ARIs in six Veterans Affairs (VA) primary care clinics. Three distinct intervention phases occurred. Educational interventions included training on appropriate antibiotic prescribing for ARIs. During the first intervention period (8/2017-1/2019), education was presented virtually to primary care providers on a single occasion. In the second intervention period (2/2019-10/2019), in-person education with peer comparison was presented on a single occasion. In the third intervention period (11/2019-4/2020), education and prescribing feedback with peer comparison was presented once in-person followed by monthly emails of prescribing feedback with peer comparison. January 2016-July 2017 was used as a pre-intervention baseline period. The primary outcome was the antibiotic prescribing rate for all classifications of ARIs. Secondary outcomes included adherence to antibiotic prescribing guidance for pharyngitis and rhinosinusitis. Descriptive statistics and interrupted time series segmented regression were used to analyze the outcomes. Results Monthly antibiotic prescribing peer comparison emails in combination with in-person education was associated with a statistically significant 12.5% reduction in the rate of antibiotic prescribing for ARIs (p=0.0019). When provider education alone was used, the reduction in antibiotic prescribing was nonsignificant. Conclusion Education alone does not significantly reduce antibiotic prescribing for ARIs, regardless of the delivery mode. In contrast, education followed by monthly prescribing feedback with peer comparison was associated with a statistically significant reduction in ARI antibiotic prescribing rates.

Abstract Background Outpatient antimicrobial prescribing is an important target for antimicrobial stewardship (AMS) interventions to decrease antimicrobial resistance in the United States. The objective of this study was to design, implement and evaluate the impact of AMS interventions focused on asymptomatic bacteriuria (ASB) and acute respiratory infections (ARIs) in the outpatient setting. Methods This randomized, stepped-wedge trial evaluated the impact of educational interventions to providers on adult patients presenting to primary care (PC) clinics for ARIs and ASB from 10/1/19 to 1/31/20. Data was collected by retrospective chart review. An antibiotic prescribing report card was provided to PC providers, then an educational session was delivered at each PC clinic. Patient education materials were distributed to PC clinics. Interventions were made in a step-wise (figure 1) fashion. The primary outcome was percentage of overall antibiotic prescriptions as a composite of prescriptions for ASB, acute bronchitis, upper-respiratory infection otherwise unspecified, uncomplicated sinusitis, and uncomplicated pharyngitis. Secondary outcomes included individual components of the primary outcome, a composite safety endpoint of related hospital, emergency department or primary care visit within 4 weeks, antibiotic appropriateness, and patient satisfaction surveys. Figure 1 Results There were 887 patients included for analysis (405 pre-intervention, 482 post-intervention). Baseline characteristics are summarized in table 1. After controlling for type 1 error using a Bonferroni correction the primary outcome was not significantly different between groups (56% vs 49%). There was a statistically significant decrease in prescriptions for bronchitis (20.99% vs 12.66%; p=0.0003). Appropriateness of prescriptions for sinusitis (OR 4.96; CI 1.79–13.75; p=0.0021) and pharyngitis (OR 5.36; CI 1.93 – 14.90; p=0.0013) was improved in the post-intervention group. The composite safety outcome and patient satisfaction survey ratings did not differ between groups. Table 1 Conclusion Multifaceted educational interventions targeting providers can improve antibiotic prescribing for indications rarely requiring antimicrobials without increasing re-visit or patient satisfaction surveys.

Abstract Background In 2011, The Infectious Diseases Society of America released a clinical practice guideline (CPG) that recommended short-course antibiotic therapy and avoidance of fluoroquinolones for uncomplicated urinary tract infections (UTIs). Recommendations from this CPG were rapidly disseminated to clinicians via review articles, UpToDate, and the Centers for Disease Control and Prevention website; however, it is unclear if this CPG had an impact on national antibiotic prescribing practices. Methods We performed a retrospective cohort study of outpatient and emergency department visits within a commercial insurance database between January 1, 2009, and December 31, 2013. We included nonpregnant women aged 18–44 years who had an International Classification of Diseases, Ninth Revision, Clinical Modification diagnosis code for a UTI with a concurrent antibiotic prescription. We performed interrupted time series analyses to determine the impact of the CPG on the appropriateness of the antibiotic agent and duration. Results We identified 654 432 women diagnosed with UTI. The patient population was young (mean age, 31 years) and had few comorbidities. Fluoroquinolones, nonfirstline agents, were the most commonly prescribed antibiotic class both before and after release of the guidelines (45% vs 42%). Wide variation was observed in the duration of treatment, with >75% of prescriptions written for nonrecommended treatment durations. The CPG had minimal impact on antibiotic prescribing behavior by providers. Conclusions Inappropriate antibiotic prescribing is common for the treatment of UTIs. The CPG was not associated with a clinically meaningful change in national antibiotic prescribing practices for UTIs. Further interventions are necessary to improve outpatient antibiotic prescribing for UTIs.

Abstract Background High regulatory burden on hospital-onset (HO) infections has increased performance pressure on infection prevention programs. Despite the availability of comprehensive prevention guidelines, a major challenge has been communication with frontline staff to integrate appropriate prevention measures into practice. The objective of our study was to evaluate the impact of educational intervention on HO CAUTI rates and urinary catheter days. Methods At the University of Mississippi Medical Center, Infection prevention (IP) reports unit-based monthly HO infections via email to respective unit managers and ordering physician providers. Starting May 2018, IP assessed compliance to CAUTI prevention strategies per SHEA/IDSA practice recommendations (2014). HO CAUTI cases with noncompliance were labeled as “preventable” infections and educational justification was provided in the email report. No other interventions were introduced during the study period. CAUTI data were collected using ongoing surveillance per NHSN and used to calculate rates per 1,000 catheter days. One-way analysis of variance (ANOVA) was used to compare pre- and post-intervention data. Results Prior to intervention (July 2017–March 2018), HO CAUTI rate was 1.43 per 1,000 catheter days. In the post-intervention period (July 2018–March 2019), HO CAUTI rate decreased to 0.62 per 1,000 catheter days. Comparison of pre- and post-intervention rates showed a statistically significant reduction in HO CAUTIs (P = 0.04). The total number of catheter days reduced, but the difference was not statistically significant (8,604 vs. 7,583; P = 0.06). Of the 14 HO CAUTIs in post-intervention period, 64% (8/14) were reported preventable. The preventable causes included inappropriate urine culturing practice in asymptomatic patients (5) or as part of pan-culture without urinalysis (2), and lack of daily catheter assessment for necessity (1). Conclusion At our institute, regular educational feedback by IP to frontline staff resulted in a reduction of HO CAUTIs. Feedback measure improved accountability, awareness and engagement of frontline staff in practicing appropriate CAUTI prevention strategies. Disclosures All authors: No reported disclosures.
